Application filed January 6, 1921.

T 0 all whom it may concern Be it known that 1, WILLIAM H. Goon, acitizen of the United States of America, residing at Toledo, Lucascounty, Ohio, have invented new and useful Detonating Alarms, of whichthe following is a specification.

This invention relates to detonating alarms.

This invention has utility when incorporated in protective or burglaralarms for windows, doors, etc.

Referring to the drawings:

Figure 1 is a perspective view, with parts broken away, showing anembodiment of the device mounted in position as to a door;

Fig. 2 is a side elevation of the device of Fig. 1 showing the device oralarm in setposition, carried by a bracket secured to a sash, so thatthe window may be open for ventilation, but further opening will causethe alarm to be tripped;

.Fig. 3 is a view of the device with the detonator holder in section,showing the device in tripped position and mounted on the cross sash ofa two part window;

Fig. 4 is a perspective view of the base;

Fig. 5 is a view on the line V-V in Fig. 2 looking in the direction ofthe arrow and having the detonator carrier shown in dotted lines;

Fig. 6 is a perspective view of the bracket,

7 which is shown carrying the device in Fig.

2; and

Fig. 7 is a perspective view of the control arm of the device.

A door 1 is shown mounted so as to swing into opening or frame 2 whichcarries screws 3, 4, with their heads slightly clear of the frame 2. Forthe screw 3 is provided end notch 5 and for the screw 4. a side notch 6in base member 7 of the alarm device. A

portion 8 of the alarm device is somewhat raised from the base 7 and hasears 9, 10, on the outer side inwardly extending to embrace the broadend of a spring member 11 shown as a flat or leaf spring with a widenedrear end 12 which may be further anchored by rivet 13 to the raisedportion 8 of the base member 7. The narrow or free end of the springmember or mounting 11 has therein an opening 14 through which protrudesa cylindrical member or holder 15 having a base flange 16 which may seatup against the underside of the member 11 when the holder 15 is inposition. This holder 15,16, may be frictionally locked or riveted tothe Specification of Letters Patent.

spring member 11. Concentrically with this holder 15 is cylindricalopening 17 therethrough having at its lower portion a peripheralannularcountersunk portion 18.

Rising from the base member 7 below this holder 15 is an upwardlyextending impact receiver 19 having a central or intermediate polnt 20as the rim fire coacting means for a blank cartridge in the opening 17of'the holder 15. Upstanding from the base member 7 adacent the impactreceiver 19, 20, is arm 21, having in its lower portion a pivot bearingproviding rivet 22 for a trigger member havmg a trigger ledge 23 and atapered extension 24 therebeyond. This trigger member 23, 24, pivotallymounted on the bearing 22 1s carried adjacent upstanding portion 21 ofthe base member 7 and the ledge 23 coacts with the under side of theholder 15 against the resistance of the spring. 11, thus holding thedevice in a set position with a blank cartridge 25 in the seat 17, 18,held away from the impact receiver 19, 20.

Upstanding member 21 of the base 7 has near its top a second pivotbearing 26 carrymg a member having an upward channel portion 27 engagedon one side by the upward projection 24 of the trigger 28, 24. Thischannel portion 27 is part of a control member pivoted on the bearing 26and having control extension or handle 28,

The trigger bearing rivet 22 has on the opposite side of the member 21an annular flange or head 29 about which may be partially wrapped a(Ll-shaped spring having one leg 80 engaging the channel position 27oppositely from the extension 24. The other leg 31 of this U-shapedspring 30, 31, enters opening 32 in the extension 24 of the triggermember 23, 24, to hold the trigger thrown toward the holder 15. 16.Accordingly the readily be installed or demounted by merely slipping thenotches into position over projecting screw heads or other points forholding the device in position where it is desired to have thedetonating alarm placed as in the instance of mounting on the door frame2, or upon window sash 33. While the mounting or spring member 11 isquite rigid for a positive throwing of the detonator against the impactreceiver, such may be lifted into raised position or set by a screwdriver or other tool drawn upward in the region of the seat 15 to pullit up into such a position that the spring 30,. 31, will throw thetrigger portion 23 out to hold the member so elevated. When thusnormally set the control member has its arm 28 swung out- I ward or awayfrom the member or base 7 In the event the one who sets the alarmdesires to leave by the openin atwhich the alarm is set, this may occur,101' the control member 28 may be swung toward the alarm device by aclosing of an opening by a door or window without setting off the alarm.At once the part has passed the control member 28, it is again thrownoutward by the spring member 30,31. However, should the closure for thisopening be moved in the reverse direction or against the undersideof thecontrol member 28, such movement will cause the channel portion 27 toact upon the extension 24 of the trigger member 23, 2 1, to draw theledge 23 away from holding position as to the mounting member 11 and theholder 15 so that the spring 11 at once swings the cartridge 25 in'theholder 15 against the impact receiver 19, 20, and for rim fire thisprojection 20 will set 01f the percussion and the detonating dischargewill result.

The device is conveniently mounted in any desired position as to theopening and may even be mounted in a position which would leave the seatdownwardly open. In such last mentioned instances, to keep the cartridge25 in the holder 15 from vibrating or shaking out, the cartridge 25 maybe at its open end slightly squeezed or distorted so that it willfrictionally engage in the seat 17 of the holder 15, 16. The device maybe charged in its set position or may be conveniently removed byslipping it out of its notches and taking it down at such times as maybe desired. Further if it is desired to leave the device in position allthat is necessary to do is to throw the control member arm 28 intoparallel relation with the upstanding arm portion 21 at which positionthe channel 27 rides to bring the spring arm 30 into seat 34: and thedevice is held inoperative and the trigger 23' is still protrudingandmaintainsthe device set, but it is set not in-a position to be thrownoil by the control member for the control member open for ventilation,instead of mounting the device directly, it may be carried by a bracket35 mounted by screws 36 on window stop 37 at the desired location forthe member 28 to project into the path of travel of thesash 33. Lugs 38,39, permit detachable mounting of the device to the bracket 35.

A detonating alarm of this disclosure is a substantial compact device ofinsured operation as to all of its mechanisms. It may not be distortedor readily disturbed when in operative position except as designed inits construction for such disturbances 'As it i made throughout ofwrought metal parts, it is of the most substantial character. Thesheet'metal base, trigger and control member are parts which are readilyand e00 nomically stamped out and the'spring portion is also asubstantial part not only oper V ating as a spring but also as amountingfor 85 the holder. The holder is a tubular member which is readilyformed to provide a seat as herein disclosed. The parts are such asmight easily be produced in quantity and as so produced may be assembledinto the devices of standard form with interchangeable parts for use insuch diverse places as may be desired by the householder or for use inor about a place of business. While-the device is shown as a cartridgecarrylng alarm of the detonating type and it is peculiarly designed forsuch utility, still the detonating features may be varied as foundconvenient in practice or to fit the conditions in which it is desiredto be used. In those 100 instances where it is desired to mount thedevice some distance from the object, movement of which object is to set011 the alarm device, in eye 10 may be engaged a wire or rod 11extending to such object.

That is claimed and it is desired to secure by Letters Patent is: V
